* Prohibit inlining of some functions to place them in ITCM-RAM

* Fixed usartTargetConfigure implicit declaration

* Moved back to SRAM1 as main RAM

* Minimized cache footprint of motor output code

* Evicted low-impact functions from ITCM

* Switched MATEKF722 and SPRACINGF7DUAL to burst DSHOT

* Switched CLRACINGF7 to burst DSHOT

* Moved UART RX&TX buffers to DTCM-RAM to avoid cache incoherency
